I would vote for scrypt, x11, lyra2rev2 and blake2s
I don't think two algos with huge farms is needed. Scrypt and X11 just as Scrypt and Sha256 imo are redundant it would be nice to show small farms and individuals some love they're part of the community big farms couldnt care less for the future of the project.
You are not going to find an algo that has no huge farms.
Scrypt, x11 and sha256 are asics.
Any "cpu" algo is botnet. Just about all blake algo are fpga.
No matter what is picked is going to have up and down sides to them.
So in a nut shell all asic algo's are asic farms. All cpu algo's are botnet and all gpu algo's are huge farms.
So where is the middle ground?
